i had the same problem and i tried all the match/paper clip wiggling techniques but nothing worked. so i tried this and for some reason it worked!!


Instructions:
1) Plug in ear phones
2) Start toggling the volume controls on your keyboard (press the volume buttons up and down continually)
3) While toggling, slowly pull the ear phones out. Remember to keep on toggling quickly!!!
4) Now actually make the volume louder by turning it up on the screen

It should now work... at least that worked for me. I guess the idea is that you are trying to tricked the computer in a weird way.

Hope it helps!!
